I own a Late 2008 MacBook running OSX Yosemite. After 12 years of light to moderate use, the internal Airport wireless card finally went bad. While replacing the Airport card is certainly possible, it is a pretty involved process that carries a certain degree of risk. Instead of disassembling my Macbook, I looked around for an alternative solution.When I found the Cudy AC650 (model WU650), I was pretty excited. Basically, I was looking for a USB Wifi adapter that was Mac OS compatible, compact in design, and had a decent range. Also, at around $12.90, the Cudy seemed like a decent value, even if it wasn’t the cheapest.One thing I was a little disappointed in was that the Cudy adapter isn’t plug and play. You do have to install a driver in order to get up and running. It is also worth mentioning that there is an installation disc included, but it is a mini-CD which is too small to work in the MacBook’s slot loading DVD/CD disc drive (it’ll get stuck if you try). Therefore, you’ll have to download the driver from the Cudy website in order to get up and running.The driver did install pretty quickly and easily. I didn’t experience any problems there. After a quick reboot of the system, all I had to do was reconnect to my wifi network, and I was back up and running again. I have about the same range as before. I found that the connection speed was great. I had no trouble achieving between 390-433Mbps (the manufacture advertises 433Mbps @ 5GHz, so this was pretty spot on).One important thing to note is that this device is only a Wifi adapter. It doesn’t offer Bluetooth. So, if you are looking for a complete solution to replace a bad Apple Airport card, you’ll want something that supports both Wifi and Bluetooth. Otherwise, you’ll need to get a USB Bluetooth adapter as well (if you use Bluetooth devices).Overall, I’m pretty happy with this Wifi adapter. It does exactly what I need it to, and it was certainly cheaper, and easier, than reinstalling a new Wifi card in my old MacBook.

I got it, I opened it up, and I was able to get online instantly with a 5Ghz connection. So Yeah, it works exactly as intended, perfectly plug-n-play. Definitely recommended if you need a wifi dongle for your rig.

Durable, easy of use

I've had it for less than two full days now, and it's already proven defective. The first bad sign was the fact that, when I downloaded the drivers and tried to install them the first time, it caused my computer to go bluescreened with an error, and restarted my computer. The second bad sign was when, hours after getting it installed and working, my internet suddenly failed and could not connect to any wifi. Unplugging and replugging the dongle back in fixed the issue, but only temporarily. I've had to unplug and replug it three times in less than two full days. The device is clearly defective. I am returning it for a refund, and will be purchasing a different wifi device after this.

This USB WiFi adapter works very well, works not only with Windows but also with Linux, and is very inexpensive. Are there better WiFi adapters out there? I think so, but this is a very good adapter for the price, and I would absolutely consider purchasing it again.

Works great on Windows 7 and Windows 10 computers. My hifi router is from Xfinity. The connection is fast and very stable.
